Application filed July 7,

T 0 all whom it may concern:

Be it known that I, CHARLES H. OSLUND, a citizen of the United States, residing at Worcester, in the county of Worcester and 'State of Massachusetts, have invented a new and useful Wiping-Down. Device, of which the following is a specification.

This invention relates to a device for wiping down the two over-lapping nds of a label which passes entirely around the article to be labeled, althoughit is capable of wiping down the edge ofa label even when it does not overlap.

The principal object of the invention is to provide for automatically wiping along the edge of the label for the purpose herein specified after the label has been placed in position by the ordinary wiping operations heretofore employed, or by any of them.

It is also an object of the invention to provide this feature in convenient and simple form adapted for use with a well known typ of wiping machine without adding any unnecessary complications to it or providing any additional supporting and guiding devices.

Further features and advantages of the invention will appear below.

Reference is to be had to the accompany- "ing drawings, in which- Fig. l'is a side view of a part of a rotary labeling machine having an attachment constructed in accordance with this invention and shown in its normal inactive position;

Several devices have been inventedfor the purpose of more smoothly and, com-,

pletely over-lapping the ends'nof a label in a case like this but so far as we aware, theyzr usually work on the principle of thewipers.

11 or, in addition thereto, the employment.

of one or more wipers operating-trans:

' versely with respect tothe length. of-the bottle. H

The mere wiping of the label=down ,by the two wipers 11 is not sufficient under some circumstances as the over-lapping ends. can not sometimes be brought into such a smooth condition as is desirable, especially,

on the conical 0r ovate surfaceof a bottle necln p .This invention is designed to provide for: positively smoothing out this over-lapping. end after it is brought into substantially, its final position. In other words, this/is. a finishing operation consisting in the wiping: and smoothing down 'of the ov'er-lapping end of the label.

The invention is shown as applied to av labeling machine which involves a rotary. table 10, turning about a center, butitrcan be applied to labeling machines in whichithe. bottle 13 to be labeled is moved rectilinearly'. or in any other way. However, on thistype ofmachine-thereis a vertical rod 13 operated by mechanism below, not shown herein asit is illustrated.

in several prior patents. ltextend s up. through a stationary sleeve 14' mounted on the table and has-a clamp 15 atwits top" adapted to clamp -down on the top: ofgthe bottle B and hold it in position against a stop 16 while the bottle passes around on' the table through -a part of a complete revolution; I have made use of these features. tosupport and guide the parts which co'nstitute the present improvement.

Mounted -below the 'rotary table, I have.

placed a cam 18in stationaryfpo'sitionand on the table I have placed a bracket 19 having a pivotpin-2O thereon for supporting a lever 21. A sprin 22 holds the operative bifurcated end of th s lever down. The other arm of the lever supports a roll 24 which entersfthe cam as the table rotates and is controlled by the side walls of the cam during the rotation of the table.

When the cam is engaged by the roll 24:, its. inner wall forces this roll out against the action of the spring 22 and the bifurcat'ed end23 moves upwardly a pin 25 which projects into the notch between the bifurcations. -This pin is mounted on a rod 26 which passes freely up through a perforation in the; table and has secured to it at the topaplate 27. This plate is provided with a cylinder 28 which moves positively with the rod" 26 and is guided'on the sleeve ll'fixed to the table. WVit-hin its upper end, this cylinder 28 carries a sliding bushing 30 which is of a general cylindrical form slidably engaging the rod 13 and has a flange 31 at the top adapted, when in the position shown in Fig. 3 for example, that is when it is raised from its normal low position, to rest on the top of the sliding cylinder 28 where it has no active function.

=-IIowever, when the cylinder 28 is in its lowermost position, as shown in'Fig. 1, the lowerend of the bushing 30 comes into contact with the top of the stationary cylinder 14 and this occurs previously to the move ment'ofi the cylinder 28 to the lowest position. The result is that this sliding bushing can move down no further and as the sleeve 28 continues to move down to the lowermost position shown in Fig. 1, the top flange 31 of the sliding bushing then acts as a stationary member and the end of a lever 33 comes into contactwith it as shown in Fig. 1. This lever 33 is pivoted on a pair of projections 34 mounted' on a'bracket 35 positively fixed to the cylinder 28. Therefore, when it comes down into the position shown in Fig. 1,,the outer'end of the lever 33 is depressed. This, by means of: a link 36, depresses an arm .37 fixed on 'a'shaft 38" supported by the bracket 35. On this shaft 38 is an arm 39 normally pulled upwardly by a spring 40 and also an arm 41 carrying a soft felt or leather wiping roller 42. Therefore, the movement of the lapping end of the label.- The cam is so" shapedthat the roll then goes down this line and performs its finishing operation on the downward strokeat the end of which the roll is drawn back into the position shown in Fig. 1 in the manner above described;

It will be seen that although the operation is performed by a cam and the cylinder 28 is raised positively and lowered by spring action, the roller 42 is pressed against the label by spring pressure due to the spring 40 and thusa gentle yielding action is secured. This constitutes a safe and positive means for effectually smoothing out a label previously wound around an article, particularly.

the neck of a bottle without adding much mechanism to the labeling machine, particularly if applied to the type of machine illustrated.

Although'I have illustrated and described only one form ,of the invention and illustrated it as applied to a single type of labeling machine, I am aware of the fact that it can be formed with many modifications and applied to numerous types of labeling mas chines without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to belimited in these respects, but what I do'claim is 1.. In a labeling machine, the combination with means for wiping a label all the way around an article and over-lapping it, of a roller and means for moving the roller longitudinally along the over-lapping end of-the label. I

2. In a labeling machine, the. combination with means for wipinga label on an article, and lapping one end over'the other, of a label pressing device, and means for moving said pressing device up and down along the over-lapping end'from one edge of the label to the other.

3. In a labeling machine, the combination with-means for wiping a label around an article and over-lapping its edge, of asupport movable longitudinally with respect to the axis of the article to be labelednand means carried by said support for effecting a pressing-and rolling action progressively: 1n astraight line from one edge of thelabel' to the other and along said overlapping part to smooth out the edge of the label and complete the wiping operation. a

4. In a rotary labeling machine, the combination of a rotary table, a rod carried thereby having means for clamping the article to be labeled down on the table, means for applying the two ends of the label around the article and lapping one over the other, and means guided by said rod for wiping down the overlapping edge of therod for wiping down the over-lapping edge of the label, saidv lever having, connections controlling the vertical position of said means.

6. In a labeling machine, the combination with a support for the article to be labeled and a clamping rod movable therewith and parallel with the axis of the article, of a sleeve carried by the table in which the clamping rod is adapted to move up and down, a cylinder slidably mounted on said sleeve, means below the table for operating said cylinder, and means carried by the cylinder for performing a finishing wiping operation on the label applied to said article.

7. In a labeling machine, the combination with a support for the article to be labeled and a clamping rod movable therewith, of a 5 sleeve carried by the table in which the clamping rod is adapted to move up and down, a cylinder slidably mounted on said sleeve, means below the table for operating said cylinder, a bushing slidably mounted on top of said cylinder adapted to rest on the top of said sleeve when the cylinder is in its lowermost position, a bracket carried by said cylinder, a lever supported by the bracket and positioned for its end to engage the top of said bushing when the sleeve is lowered and tobe freed therefrom by the raising of the cylinder, and a roller wiper supported by said bracket and controlled by said lever.

8. In a wiping device, the combination with a vertical guiding rod, a sleeve surrounding it, a bushing mounted to slide on said rod above the top of said sleeve, a

member slidable up and down the sleeve along the outside and adapted to move the bushing up and down, a bracket on said member, a lever carried by said member and having one end in position to be con trolled by the position of said bushing, a pivoted arm having a, rolling wiper thereon, means carried bysaid bracket for applying -a spring pressure to said arm to,

force the roller toward the article to be labeled and means carried by said bracket and operated by said lever for positively moving the roller back out of operative position when the said member is moved to one extreme position, whereby the roller willoperate along a label during a part of the motion of said member and will then be retracted therefrom.

In testimony whereof I have hereunto affixed my signature.
